Does anyone believe...?

I would think by now we all know about Chris Benoit. I don't follow wrestling, but does anyone else find it strange that this year alone, many other wrestlers, such as Scott "Bam Bam" Bigelow and Mike "Awesome" Alfonso have commited suicide? Do you think this is all a coincidence, or that the known use of steroids in the WWE has a lot to do with it? What do you think the WWE should do about this?
